WIND OWFASTENER.

Application led June 2, 1920. Serial No. 385,881.

To all whom 'it 'may concern:

Be it known that I, 'WILLIAM MILLER, a citizen of the United States,residing at Amesbury, county of Essex, State of Massachusetts, haveinvented a certain new and useful Improvement in Window-Fasteners, ofwhich the following is a specification, reference being .had therein tothe accompanying drawings.

The invention relates to a new and improved type of window fastener andantirattling device, which is particularly adapted for use on thewindows of vehicles.

The object of the invention is to provide a device which will secure thesash in any desired position and at the same time prevent it fromrattling. Another object of the device is to provide a handle by whichthe sash may be liftedp The invention will be fully understood whentaken in connection with the accompanying drawings, and the novelfeatures thereof will be pointed out and clearly defined in the claimsat the close of this specification.

In the drawings, Figure 1 isa view in elevation of a vehicle doorequipped with a device embodying the invention.

Fig. 2 is an enlarged sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is an enlarged sectional view taken on line 3--3 of Fig. 1.

Fig. 4 is a detail of the latch.

Referring now to the drawings, I have shown my improved lock applied toa window in a door of a motor vehicle, as it is particularly adapted forthis use.

At 11 is indicated the door which is provided with a sash 4 equippedwith a device embodying the invention. The sash is slidably mounted inthe window frame 13 which is provided at each side thereof with verticalchannel members 5. The channel members 5 are covered with aresilientmaterial preferably felt, as shown at 14 in Fig. 3.

A notched bar 6 secured to the garnish rail 13 of the window frame byscrews 15 coopera-tes with a latch 16 pivotally mounted on the sash 4 toform the fastener and antirattling device embodying the invention.

The latch 16 is mounted on the sash in the following manner Attached tothe glass 17 at each side thereof are binding members 8 and 9, which areU-shaped in cross section and which extend the full height of the glass.The binding member 8 is provided with a flange a as shown in Fig. 3 towhich is secured a bracket 18 which forms a support for the latch 16 ofthe window fastener.

The bracket 18 is secured to the flange by rivets 19 and has twolaterally extending ears 20 adapted to receive the pivot pin 21 onlwhich the latch 16 is mounted.

Surrounding the pivot pin 21 is a coiled spring 22, one end of whichengages the bracket rigidly secured to the sash, and the other end ofwhich bears on the latch to normally hold it in engagement with one ,ofthe notches 7 in the bar 6.

The latch is provided with a handle b on one side of its pivot, whichmay be used as a knob to move the sash to any desired position, and atthe side adjacent the window frame is formed with a tooth c whichengages the notched bar 6 attached to the garnish rail of the window ordoor frame.

As will be seen by reference to Fig. 4, the tooth c of the latch isformed in the shape of a wedge, and the notches 7 in the bar 6 are givena corresponding shape (see Fig. 2). This construction provides meanswhereby rattling produced by tendency to an up and down movement iseliminated.

It will also be seen that the action of the latch spring fastens thesash to the window frame and the pressure of the spring preventsvibration of the sash in and out relative to the window frame.

The construction is therefore such that the window sash is held frommovement in and out and also vertically, so that a single device of veryinexpensive construction holds the window from all movement, and forms afastener as well.

I have shown but a single device embodying my invention applied to thewindow illustrated in the drawings but in the case of a very wide sashit may be advisable to use one at each side thereof.

What I claim is 1. In a device of the character described and incombination with a window frame having a notched bar secured thereto, awindow sash, a latch pivotally mounted on the said sash, the axis of thepivot being parallel with the notched bar and a spring acting on thesaid latch to cause the point of the latch t0 engage a notch in the saidbar and by its reaction to restrain the sash from movement in and outrelatively to the frame.

2. ln a device of the character described and in combination with awindow frame having a notched bar secured' thereto, a window sash, feltinterposed between the sash and the frame, a latch pivotally mounted onthe said sash, the axis of the pivot being` parallel with the notchedbar and a spring acting 0n the said latch to cause the point of thelatch to engage a notch in the said bar and by its reaction to restrainthe sash from movement in and out relatively to the frame,

3. In a device of t ie character described, a window frame, a sashhaulinga binder member secured to the 1(glass, said binder member havingon one side a lng` bent up therefrom, a latch secured to the said lug, anotched bar on the frame, and a spring to cause the point of the latchto enga-ge one of the notches in the said bar.

4. ln a device of the character described, a window frame, a sash, alatch pivotally mounted on the sash and having a wedgeshaped tooth withtwo inclined converging faces, a. notched bar secured to the windowframe, the notches in said bar corresponding iny shape to the tooth onthe latch to cooperate therewith and restrain the sash from movement upand down relatively to the window frame.

5. ln a device of the character described and in combination with awindow frame having a channel for a window sash, a felt facing for thewall of the channel7 a sash slidable in said channel, a notched barsecured to the window frame, a latch pivotally mounted on said sash, anda spring which acts on said latch to normally cause the latch to engagewith a notch in said bar, and to cause the sash to have an elasticpressure against the felt facing of the channel.

6. ln a device of the character described, a window frame, a. sash, alatch pivotally mounted on the sash and having a wedges shaped toothwith two converging faces at equal angles of inclination, a notched barsecured to the window frame the notches in said bar having` twoconverging faces corresponding with the converging faces of the tooth,and a spring which causes the tooth of the latch to engage with one ofthe notches in a wedging manner.

.7. ln a device of the character described, a window frame, a sash, alatch pivotally mounted onv the sash and having,` a wedgeshaped toothwith two converging` faces at equal angles of inclination, a notched barsecured to the window frame.y the notches in said bar having' twoconvergingfaces corresponding with the converging` faces of the tooth,and a spring which causes the tooth of the latch to engage with one ofthe notches in a Wedging manner, the converging faces of the notches andof the tooth being` converged when viewed in a horizontal direc tion,and the sash being movable vertically.

ln testimony whereof l affix my signature.
